The WHO Child Growth Standards

The idea of this app is to visualize WHO child growth standards data. For this project we focus on the age/weigth data for boys and girls.

These standards were developed using data collected in the WHO Multicentre Growth Reference Study.

The Data

The data contains the percentiles of the weight by age of the child. See this interactive plot of the data:

App

The app is splited in three parts.

  • server.R loads the data and contains the business logic
  • ui.R describes the user interface
  • prepare_data.R is responsible for downloading and preprocessing (extracting) the data from the WHO page. This part is only necessary if you want to redownload the data.
